In this review, based on few comparative and randomized studies on treatment of impacted proximal ureteral stones, the results of SWL were inferior to those obtained with PNL, URS and LU (laparoscopic ureterolithotomy).

It is possible that following a long period of obstruction caused by the stone; pre-SWL stenting might have been of value both for the kidney and for improving the results. That is an approach (with internal stent or ureteral catheter) that I personally have applied successfully in many patients with impacted ureteral stones.
